Extract Directly from Time Machine

Normally you use Time Machine to restore lost data in a file like this: within the Time Machine interface, you go back to the time the file was not yet messed up, and you restore it to replace the file you have now.

You can also elect to keep both, but the restored file takes the name and place of the current one. So, if you have made changes since the backup took place that you would like to keep, they are lost, or you have to mess around a bit to merge changes, rename files, and trash the unwanted one.

As an alternative, you can browse the Time Machine backup volume directly in the Finder like any normal disk, navigate through the chronological backup hierarchy, and find the file which contains the lost content.

Once you've found it, you can open it and the current version of the file side-by-side, and copy information from Time Machine's version of the file into the current one, without losing any content you put in it since the backup was made.

Power Macs outperform SGIs?

As a Mac developer whose current product, Jet Stream Color Image Server, runs on SGI hardware (from the "Purple" Indigos and the Indigo 2 to the Indy machines), I can tell you they don't compare to Power Macs in price/performance.

The Indigo 2 that Mr. Showker saw (TidBITS #227) was probably the standard SGI Indigo 2 demo machine that has a 2 GB Barracuda hard drive, 128 MB to 256 MB of RAM, and is running minimal system software. A bare Indigo 2 machine starts in the $15,000 range. Add $3,000 for the 2 GB drive (SGI charges more), $10,000 for 128 MB of RAM, and $6,000 for a monitor with 24-bit graphics and Mr. Showker's "All for a few dollars more than a dressed-out Power Mac" starts at $33,000. A Power Mac 8100 has faster Specmarks, starts at around $5,000 and with an added $2,000 for the Barracuda drive and $4,000 for the RAM, you're at $11,000 for a machine that can do more when the truly native version of Photoshop 3 arrives. [And then there's the fact that SGI Photoshop is reportedly two to three times more expensive than Photoshop for the Macintosh. -Adam]

I have yet to see SGI Photoshop run at even Quadra speeds on our Indigo 2 and Indy machines when they are networked in our standard work environment. I was at Macworld in January where SGI was showing how the Indy at $4,995 was better than a Quadra. The folks from Corel were saying why they weren't doing development for the Mac anymore and why you should buy the Indy with their program. I then asked the Corel demonstrator the minimum machine required, and he said an Indy ($5,000), 2 GB hard drive ($3,000), 96 MB of RAM ($8,000), and 24-bit video ($3,000 to $4,000 for a new monitor and $2,000 to $3,000 for a 24-bit video card). The machine recommended to run CorelDraw for SGI cost over $22,000!

In case you're wondering, why do we use the SGI? Because for price/performance it is the fastest Unix workstation out there. We know the machines needed to run our software cost our customers $20,000 to $30,000, but we also have the fastest Adobe PostScript Level 2 RIP available and they view that as the price for speed and stability. My goal is to move to a PowerPC 604/620-based Mac running System 8 (Copland) in two years so we can get the pre-emptive multitasking and memory protection we get on the SGI along with the price/performance of a Power Mac.
